Python Basics Functions Challenge Task 1

I am having trouble with the following code. It looks like the problem is with the print statement. I will just retype it here since I can't figure out how to cut and paste it:

list = [1,2,3]
def add_list(arg):
    total = 0
    for item in arg:
        total = total + arg[item-1]
    return total
def summarize(arg):
    print("The sum of {} is {}").format(arg, add_list(arg))
summarize(list)

hey elizabeth , im actually stuck in the same problem right now. i cant seem to find it. 

list = [1,2,3]

def add_list(list):
  total = 0
  for i in list:
    total += i 
  return ("The sum of {} is ".format(list),total)

this is the code i have so far. in the instructions it doesnt say anything about a second function. but in the code box it says there should be two.

Sorry about that, it looks like Treehouse did keep the formatting I used when I typed in my code it. Also, take out the end parenthesis before the .format. It is crashing on the last line.

Michael, Should you have an end parenthesis following .format(list? I think you need to take that out, and then add another one after total).

hey, yeah i got it working. this is the code i used to solve mine tho 

list = [1,2,3]

def add_list(list):
  total = 0
  for i in list:
    total += i 
  return total

def summarize(total):
  return ("The sum of {} is {}".format(list,total))

I got it to work with:

def summarize(list): return ("the sum of {} is {}".format(list, add_list(list)))
